Make sure she's warm enough, has loads of fresh water. Look up botulism threads, consider giving her activated charcoal (over the counter, comes in capsules you can open up and put in her water - it is said to bind to toxins).

it was a niacin problem i think, i put them on nutri-drench a good strong batch of it in their waterers and in an hour and a half the symptoms stopped, the rest stopped over night, shes still a little slow but 100% better than yesterday.
